Anyone for a piggyback? Poppy and Boris are best buddies (Picture: Apex)

He might be Britain’s biggest pig, but the sheer size of Boris – who could be going in the Guinness Book of World Records – still didn’t dissuade Poppy the terrier from hopping on his back and hitching a ride.

The fearless canine lives on Chyvarloe Farm, near Helston in Cornwall, with Boris, who is more than 7ft long, 3ft tall and weighs more than half a ton.

The monster porker’s owners – Paul and Charlotte Parfitt – believe the four-year-old pig could be Britain’s largest and have written to Guinness in the hope of getting him into the book.

If he was made into sausages, 82st Boris would be big enough to create more than 6,000 of them – which would feed a family of four for two years.

But the Parfitts say they no longer have the heart to send him to the slaughterhouse, despite buying him as part of a one-off batch of the animals with a view to fattening them up for food.

Mrs Parfitt said: ‘In the first batch we ever purchased was Boris – a pig who was to prove truly phenomenal in growth and personality.’

The super-swine sires 70 piglets a year and munches his way through 3kg of rolled barley and wheat per day. S’nout to be sniffed at.
